Your 3CX Extension Via a Multi Net SIM

Your 3CX Extension Via a Multi Net SIM delivers your extension to your mobile. Working on both smartphones and feature phones and delivered using either a conventional SIM or eSIM it means all 3CX calls are delivered using the included minutes over the cellular network. 

All Phone Types Supported 


Any dual SIM iOS or Android smartphone will support the additional SIM allowing you to retain existing calls, texts and data package while enabling your 3CX extension via the iOS or Android smartphone.

Feature Phones

You can choose any feature phone and either add a second SIM where supported meaning you retain your existing mobile number calls and texts package using the second SIM to make and receive your 3CX extension calls. You may also choose a low cost dedicated single SIM phone and drive all your 3CX calls over that phone. 

Multi Net Service; one SIM to Access All UK Networks 

These SIMs default to the Vodafone and O2 networks, should they be unavailable they will default to EE which means maximum availability across all UK networks. The SIMs/eSIMs run across all UK networks maximising availability and roam like home in UK, EU27 and USA. 

Calls are made and received through your 3CX PBX and delivered over the cellular network meaning data is not required for calls only.
